Hi i have a '02 TD5 that has air getting into the fuel system Have re place the fuel pressure regulator after it would not start as it was leaking . Have since got air being sucked in too the fuel system have checked all gasket s ,O rings , replacced fuel filter housing complete with filter and water sensor , fuel pump . I have checked all fuel lines from front too back and can find no fuel leak but still sucks in air . When it sarts it will tick over ok but will only drive for about 1 mile then dies but will start after it is bled again . Anyone out there had the same problem or any ideas what it could be any help greatly appreciated . Have just finnished checking the hole of the fuel system but still no luck can find no leaks or cracks anywhere
